Best WiFi analyzer apps for Android in 2026

These Android apps look at wireless networks from different angles. Some graph channels and signal strength, some scan your local network for devices and open ports, and a few watch the cellular side or put connection details on a home screen widget.

Fing has the largest audience here, with over 50 million installs on Google Play. Pick by the job you need done: choosing a channel, finding devices, or logging radio data. Where an app has no Google Play figures in our records, we say so on its entry.

Network Scanner: best for finding devices and open ports on your LAN

3.3 MB Verified file

Network Scanner finds the devices on your local network and lists their IP addresses, hostnames and device types. Discovery uses a ping sweep with TCP fallback, ARP, mDNS, SSDP and NetBIOS. The port scanner can check common ports with service and version detection, or run through all 65,535 ports.

The MAC and vendor lookup runs from a bundled offline database. The app is free, shows no ads and is licensed under GPL-3.0-only. At 3.3 MB, it is a small download.

It is a device and port tool rather than a channel analyzer, so it will not help you pick a less crowded channel.

Pros

  • No ads, free, and open source under GPL-3.0-only
  • Several discovery methods plus a scan of all 65,535 ports
  • Small 3.3 MB package with an offline vendor database

Cons

  • Showing MAC addresses on Android 10 and later needs optional Shizuku or root access
  • No Google Play rating or install count
